Answer:
A. The dominant factor, or allele, is for round seeds.
Explanation:
Gregor Mendel discovered the principles that governs inheritance. During his numerous experiments, he conducted a cross in pea plants involving a single character. This cross is called MONOHYBRID CROSS. In one of these monohybrid crosses, he observed the gene for seed shape in pea plants. He discovered that two alleles are responsible for the expression of this gene: round allele (R) and wrinkled allele (r).
He crossed plants that produced only round seeds i.e. homozygous RR and plants that produced only wrinkled seeds, rr. He observed that the F1 offsprings were all round-seeded. This made him to propose his LAW OF DOMINANCE, which states that an allele is capable of masking the expression of another in a gene. He concluded that the round allele is covering the wrinkled allele in a heterozygous state, since it is expressed over it. He then called the round allele, DOMINANT allele and the wrinkled allele, RECESSIVE allele.
A scientific theory can be made by testing something.
An amino acids between the two species, there are twenty positions along the sixty amino acids sequence that are identical between the aphid and the bacterium Pantoea. A computer can be used to compare these quences from the rest of the species to the aphid sequence.
The plant should be de-topped at least 4 cm above the surface of the soil.
The stump of the plant is tightly fitted with the apparatus.
Tube is filled with water, not completely but at least one-fourth
Remember to note the initial water level.
Note the final water level and draw interference by calculating the difference between two levels.
